Japan's boffins: Global warming isn't man-made
Climate science is 'ancient astrology', claims report
2. The limits of modeling aerosols and clouds
The indirect effect of aerosols and aerosol generation as the greatest uncertainty is becoming widely recognized, but fundamental, naturally spontaneous (especially oceanic) aerosols are not yet well understood. Dimethyl sulfide (DMS: CH3SCH3) of biological origin is thought to be a primary source of sulphuric aerosol formation over oceans, but the process of cloud cores forming from DMS is not sufficiently understood. According to recent physical models, the percentage of involvement of cosmic ray ionization processes is not well understood.
Furthermore, the types of aerosols and the ways they affect climate systems are not well understood. The increasing number of aerosols, in this case, augments precipitation, but if it increases too much, water droplet diameter will decrease and cloud generation will be renewed, and the albedo will be changed significantly. Thus, the fine-scale physical processes of clouds causing feedback in geological climate fluctuation now clearly points at this as a decisively material effect.
However, the discussion of the properties and life span of aerosols in clouds in the IPCC 4th Evaluation Report is inadequate.
3. Predictability and estimation rules
The 4th Evaluation Report is confident of the reliability of its assessment that previous data does not differ from its model. But a more effectively persuasive assessment of its predictive ability has not come forth. This is like the ancient Greek Thales predicting solar eclipses, future predictions should be tested in practice. Again, by means of short metaphase models and domain models, future information feedback can be isolated in hindcast experiments (reproducing the past according to the model) and quantitatively compared to long term climate predictions assessments.
4. Conclusion: Anthropogenic global warming theory still hypothetical
To summarize the discussion so far, compared to accurately predicting solar eclipses by celestial mechanics theoretical models, climate models are still in the phase of reliance on trial and error experiential models. There are still no successful precedents. The significance of this is that climate change theory is still dominated by anthropogenic greenhouse gas causation; the IPCC 4th Evaluation Report's conclusion that from now on atmospheric temperatures are likely to continuously, monotonously increase, should be perceived as an unprovable hypothesis; it will be necessary investigate further and to evaluate future predictions as subject to natural variability. ®
